Remove the caulking nut (A) from the front axle.

Tightening torque :

294.2 - 313.8 N·m (30.0 - 32.0 kgf·m, 217.0 - 231.5 lb·ft)

•	The driveshaft lock nut must be replaced with new one. When replacing the drive lock hub nut, use only the nut with screw thread (A) on the end.

•	When replacing the drive lock hub nut, use only the nut with screw thread (A) on the end.

•	Tighten the driveshaft lock hub nut to the specified tightening torque, and caulk by using a chisel and hammer.

•

If there are two key seats, perform on all two seats.

Caulking depth (A) : 1.5 mm (0.0591 in)

Disconnect the driveshaft from the axle hub by using the SST (09517-4E000).

Removing the driveshaft, do not force pull or over deflect the axle.

10.	Separate the front driveshaft (A) from the knuckle assembly (B). [LH] [RH]

[LH]

[RH]

•	Do not insert the pry bar too deep, as this may damage the oil seal.

•	Do not pull the driveshaft by excessive force as it may cause components inside the joint kit to dislodge resulting in a torn boot or a damaged bearing.

•	When using the pry bar, be careful not to damage the transaxle and joint.

•	Plug the hole of the transaxle case with the oil seal cap to prevent contamination.

•	Replace the retainer ring whenever the driveshaft is removed from the transaxle.

Installation

1.	Install in the reverse order of removal.

2.	Check the front alignment. (Refer to Suspension System - "Alignment")
